Right now she looks like a scared cat with her arse hiked up. , fortunately lowering the rear
Is simple and cheap....2 10inch grade 8 bolts. Front not so easy.

View out 27 y.o. master cylinder...first $98 expended. Money pit begins. To be continued I'm sure

Now chasing a electric cooling fan issue. But I did snag complete set of new polyn suspension bushings on a corvette forum at a good price!

[aschen]

Glad your saving that c4 from the scrap yard


I have been thinking alot about a c5 autox/hpde car lately. The performace and track parts add up quick though so Im trying to think about a reasonable budget I can stick too.

[Dueller]

I'm building this for the GRM $2016 challenge so due to EXTREMELY limted budget Contraints, I'm making a lot of compromises I would do differently if I were trying to build a competitive car for a specific class. But it is a fun exercise for chits and giggles.

So has your girlfriend lightened up yet or is she still worried the C4 will get more attention than her?


BTW I'm not into C4s but for $400, I'd have one in my garage too!

[Dueller]

Me neither, Mike. Just kinda fell into this. Yeah....: has calmed down

[Dueller]

First major build crisis.... The spaghetti ma's of brake lines going into ABS system is rusted and leaking. Anybody see any problem withtotally eliminating primitive ABS and fabing old school lines and a proportioning valve?

[Heel n Toe]

I don't see why you couldn't do that... seems like that would certainly be optimum for autocrossing and track days.

However... unless someone here chimes in with some solid advice based on direct experience (fastfred? anyone?), it might be a good idea to try to ask around on some Vette website forums to find out if disconnecting the ABS-related electrical/computer stuff could cause unknown cascading problems that you don't want.

[Dueller]

Thanks for the thoughts,h&t..I may just yank every bit computer related stuff out including fuell injection,, slap manifold, a Holley and an MSD and go totally old school,

[gt350mike]

I agree.....nothing wrong with going old school.

Iffn I remember correctly, a guy we used to AX with ran a C-4 at streets of willow once or twice with the PCA. Don't remember his name but his initials are Steve Malmz

It was a stock version with 350 hp, not a Z oh whatever.

I believe he commented on the weight and also the brakes faded badly, but other than that he had fun it it.
Nothing that couldn't be fix or compensated for.

Get out the $$$, this will be a $10k four hundred bucks corvette soon! Great thing is that it will be worth about 2k when you are done!

While I would probably pull the ABS as well, I don't think it is wise to go back to carbs from FI. I thought that engine had a pretty decent FI. At least decent enough for a heavy automatic pig!

LOL....I heard that. My mechanic savant agrees on f.I. he thinks we can tweak it. It's an L98 monitor... Low reving torquer...250 bhp but something like 350 ft lbs of torque at 4400 rpms.

[porsche4life]

Jim I was poking around and I can get you the brake valve you need. What thread pitch do you need on the connections?

[Dueller]

I'll check and let you know, Sid.

Alright awright awright.......

Down to nut cuttin' time.

SO FAR I HAVE MADE THE following mods:
Completely new brake system...rotors, calipers, lines including hardliners,master cylinder, etc
New shocks
All new poly suspension bushings
Steering rack and poly bushings
Bump steer kit
Balll joints new
Sway bar bushings
Plugs, plug wires
All new filters
New CAMS spec 200 treadwear tires

So there's only $255 left in challenge budget unless I sell some of pull off parts (not much of a market for clapped out c4 parts I've found)

So what would you spend it on? Not enough to do any meaningful motor or suspension work.

Damn I've got a flux capacitor Jim, only $256. Shame about your budget.

[Heel n Toe]

Is it gonna be street legal? If so, there will be insurance costs, registration, and plates... that might finish up your budget.

But I'm guessing you're not gonna replace that rear glass, and that would be required to make it street legal, so...

...it's only gonna be a track and autocross toy and will be trailered to events.

I vote for the next expenditure to be for a fresh hacksaw blade so you can sever the exhaust right in front of the mufflers. And maybe a few bucks more for a coupla glasspacks just to soften the tone a bit.

BTW, used tires would've probably been okay. Heh heh.

[Dueller]

Hey Heel....you're from south carolina. I thought like Mississippi even farm tractors are street legal in SC.

All license, registration, ins etc is exclude from budget.

But FWIW the lifetime antique tag was $30. Got it insure as a recreational classic driven less than 5000mi per year for "shows, car events, rallys". That runs about 175$ a year. This ain't no trailer queen baby.

The irony is strong
